A medium drying device includes a transport roller pair as a transport unit that transports a medium and a heat roller pair as one heating unit that heats the medium transported by the transport roller pair and is provided in a transport direction of the medium, in which the medium is configured to be transported to a heating area by the heat roller pair a plurality of times.

A sheet feeding device includes a reversing roller, a guide member and a rotatable member. The guide member includes a curved portion to curve inside a first surface of the sheet and guides the sheet along the curved portion in contact with a second surface opposite to the first surface of the sheet in a first direction. The rotatable member disposed opposed to a sheet guide surface in the curved portion with a gap and is rotated by contacting with the first surface of the sheet. When the sheet is fed by the reversing roller in a second direction, the rotatable member is rotated by contact of the first surface of the sheet with the rotatable member.

For a printing apparatus, a first conveyance speed for a first printing medium is determined according to first print data to be printed on the first printing medium and a second conveyance speed for a second printing medium is determined according to second print data to be printed on the second printing medium that follows the first printing medium along a conveying path. In a case where the second conveyance speed is equal to the first conveyance speed, a conveyance operation of the second printing medium is started before the first printing medium is discharged from the conveying path. In a case where the second conveyance speed is different from the first conveyance speed, the conveyance operation of the second printing medium is started after the first printing medium is discharged from the conveying path.

A rotating device includes: an opening-closing portion supported so as to be openable and closable with respect to a support body; a drive unit provided on the support body; a first rotating body provided on the support body and rotated by a drive force of the drive unit; a driven portion provided in the opening-closing portion; a second rotating body provided in the opening-closing portion, rotated by a transmitted rotational force, and transmitting the rotational force to the driven portion; and an annular body formed in an annular shape, wound around the first rotating body and the second rotating body, maintaining the winding state in both an open state and a closed state of the opening-closing portion, and transmitting the rotational force of the first rotating body to the second rotating body.

A printing apparatus includes a printing unit, a first conveyance unit configured to convey a print medium in a conveyance direction, a second conveyance unit configured to convey a print medium printed by the printing unit, on a downstream side in the conveyance direction of the first conveyance unit, and a control unit configured to perform reduction control of reducing an overlap amount of a preceding print medium and a succeeding print medium, from an overlap state in which the succeeding print medium overlaps a trailing edge of the preceding print medium. The reduction control includes control of conveying the preceding print medium conveyed by the second conveyance unit faster than the succeeding print medium conveyed by the first conveyance unit, in a state in which the first conveyance unit is capable of conveying the succeeding print medium.

A magnetic-ink reading device includes a housing and a conveyor in the housing. A medium inlet and outlet port for inserting and pulling out a medium printed using magnetic ink are in the housing. The conveyor conveys the medium along a conveying path. The magnetic-ink reading device includes a magnetizing mechanism configured to magnetize the magnetic ink of the medium on the conveying path and a magnetism detection head disposed near the magnetizing mechanism and configured to read magnetism of the magnetized magnetic ink. The magnetic-ink reading device includes a reversing mechanism provided on the medium inlet and outlet port side of the conveying path and configured to reverse front and rear surfaces of the medium on a reversing path on an inside. The reversing mechanism includes a retraction path for temporarily retracting the medium when the magnetism of the medium is read by the magnetism detection head.
